There are still 18 games to be played, one direct duel, 54 points to be potentionally reached. The question about LaLiga's champion will be answered at the end of the season, not now. The league wouldn't have been won if we would have been 7 points up front or isn't lost, because the blancos lead by 7 at this point. If we win 15 out of these 18 games, I'm confident we'll win LaLiga. 84 points doesn't sound too much, but there is no consistent 90+ points team this season if Madrid keeps playing this way as well.
And we have an easier second half with more home games. Obviously it will also depend on the referees. If they keep robbing us, we have no chance of winning 15 games.
